The image, as you might be able to see, features 5 individuals posing on the cover of an algebra textbook, each holding an algebra textbook themselves. What is interesting is the fact that the algebra textbooks they are holding appear to be identical to the textbook they appear on - including images of themselves. Whilst the logical explanation would be that the books were greenscreened and edited on in post processing before publishing, the idea that a photo could be taken which includes the content of the photo itself within it opens up an interesting concept regarding either the book itself or the device used to photograph it.

I've had a few ideas, and am hoping to get some brief feedback on the community's opinions of said ideas in refards to if any closely resemble any other SCPs, or otherwise seem cliche to the site in a way I'm not familiar with.

The ideas are as follows:

Paradoxical textbook. The book contains record of an unusual mathematics system, rooted in the concepts and appearing to be at the level of pre-college algebra, however it details application and usage of a system of maths that is foreign, but accurately works in describing many SCP items that would otherwise lack any form of mathematical modelling or understanding due to their anomalous properties. An anomaly exclusive math system, if you will. Due to the pre-college level of the book, it does not have an advanced enough application of this mathematical system, so will be under research by foudnation mathematicians to extrapolate its information to more advanced concepts of math. With this idea, the book itself displays no anomalous properties, only the application of its content is anomalous.

Book following the wrong laws of reality. Foundation unknown conditions caused a photograph to be taken of two separate moments in time simultaneously, resulting in the visual paradox in the image. Visual exposure to the image displaces an individuals own perceptions to match a logic that allows the picture to sustain itself. This ultimately results in the rejection of standard laws of reality and the user perceiving the existing world to be the result of a post-ZK-CLASS End of reality scenario where the laws of physics break down, and believe the world is merely a fragmented, warped remains of a prior reality. Ultimately results in an individual being permanently unable to mesh with society or ever accept the world as is, including suicide accidental death due to misunderstanding the laws of the world and performing fatal actions. If I went for this idea I would intend to write it as to imply subtly that a ZK-CLASS End of reality situation had indeed happened, and the entire world and universe we know is merely a shattered and warped remainder of what once was.

YOUR FACE HERE! This one's a simpler idea, a textbook that through some process entraps readers in its cover who own the textbook. As the textbook is used, the textbook updates itself with the further knowledge the individual has regarding algebra as a way to keep itself updated. In the process of taking the reader's knowledge, it takes them with it and implants them on the cover, holding the textbook and updating its edition and year of publication to the date that this occurs.

Variable. The textbook applies algebraic concepts in a more literal, real world scenario. Normal objects are replaced with variables, which are then replaced by copies of other things. In its cover, the books the subjects were holding were denoted as a variable, and replaced with a copy of itself. I need to develop this idea more, regarding how what real world items would be denoted as variables and systematically replaced with copies of other items. Currently I believe the best way to go about that would be that anyone who studied from or learned algebraic material from the textbook would then become an incident of this SCP-XXXX-1, where they then will slowly modify things every time they encounter a real world mathematical problem which uses the textbook's content. Possible applications of this effect include: SCP-XXXX-1 is hosting a large dinner party, and has ordered 100 kilograms worth of catering. How many people can she host at this party? Any math question, whatever is the "thing" that needs an amount be calculated, will be replaced by an arbitrary item to fill that gap. In this case, she may invite, say, 100 people, which is how many 100kg of catering can feed, but those 100 people then become replaced by 100 identical copies of an arbitrary human. Maths does not require them to be individual. Whilst this could be harmless in some instances, for example "How many tomatoes do I need to make 2 litres of tomato sauce" would result in the tomatoes purchased becoming all identical to one another, and may indeed be beneficial because of quality consistency, however with high level leaders it may quickly spiral out of control. The President is making a decision, "With a budget of 3 Million dollars, how many people can the country afford to put on food stamps?" Suddenly the lives of however many people that would feed that rely on food stamps become arbitrary copies of a basic human. As such, exposure could easily result in an inadvertent end to humanity as we know it. Still remains "Safe" because it does not do anything to seek out readers, so passes the box test easily. Just lock it somewhere where someone won't read it.

And please collapse long posts. ~Zyn

Hopefully I can make up my mind between these, and you can help out by giving feedback to the concepts.

…and you might run into people who will see it, roll their eyes, and think, "this is just like when someone tried to SCP-ify that blue-black/white-gold dress".

Also, you've currently got way too much focus on the base abilities of the potential objects, some aspects of which are already seen in existing articles.

To quote vezaz, "Get away from "type of object" or "sort of creature" and instead start thinking about stories you want to tell. Start looking for moments in your everyday life that give you pause, that are unusual, or that make you go off into a daydream. Then think about bringing the reader to that same moment."

What's the story that you want to tell with this object? Why does it exist? Does it have a purpose? Was it ever special to someone, was anyone ever special to it?

Biggest take-home here was on the image being noted on reddit. Seeing it was much more widespread in knowledge than I was initially aware… put me off of the idea entirely. Thank you for pointing that out as well as your advice towards designing future endeavors.
